[PATCH] D69111: [X86] Emit KTEST when possible

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

What's the benefit of this? We already turn KORTEST+KAND into KTEST at the end of isel. I was trying to favor masked compares instead of keeping to registers alive into the ktest. The patch for that was here https://reviews.llvm.org/D56246
